Specification of Letters Patent.

Patented Mar. 19, 1918.

Application filed November 20, 1916. Serial No. 132,329.

To all whom it may concern:

Be it known that I IRA E. STUMP, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification. 1 7

My invention relates to improvements in mechanical movements, and more particularly to that class or type in which reciprocatory movement is converted or trans formed into rotary movement through the medium of a suitable spiral suitably arranged relative to and cooperating with the adjacent parts.

The primary object of the invention is the provision of a generally improved mechanical movement of the class or type above indi cated, capable of a large variety of uses and applications, as well as one which will be exceedingly simple in construction, cheap of manufacture, and efiicient inuse.

A further object is the provision of an improved spiral member interposed between the reciprocatory and rotary members together with an improved method of mounting the spiral member and bringingthe same into and out of clutched relation with one oi said members upon the initial advance and return movements or strokes of the said reciprocatory member whereby rotary motion will be imparted to the rotary member.

A still further object is the provision of an improved spiral and spiral clutch together with improved means of mounting and combining the same in cooperative relation to the various working parts in the particular article or device in which the improved movement may be embodied. I

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, illustrated in some of its embodiments in the accompanying. drawing and particularly pointed out in the appended claims.

Referring to the drawings, forming a part; of this specification, Figure 1, is a central. longitudinal sectional view of a screw driver embodying the improved mechanical movement, the rotary member and spiral being shown in clutched or locked engagement with the reciprocatory or handle member when the latter is in its most advanced position whereby the blade or shank portion of the screw driver is locked for use as an ordinary screw driver.

Fig. 2, a similar view, the rotary or shank portion of the tool being in its intermediate position whereby the same is actuated and glven a rotary motion by the spiral through the advance or forward movement of the reciprocatory member or handle.

Fig. 3. a view of the spiral member detached.

Fig. 4, a similar View of the shank or rotary member detached.

Fig. 5 a cross sectional view taken on line 5-5 of ig. 1. r

Fig. 6, av View of a modification of the improved movement applied to or embodied 1n a spinning top.

Fig. 7 a view of the same detached from the top body and showing the spiral member moved longitudinally out of engagement with the rotary member during the return movement of the reciprocatory member preparatory to giving the spiral and rotary members a new working impulse.

Fig. 8, a longitudinal sectional view of a handle or reciprocatory member embodying a further modified form for use'in connectionwith an article or utensil, such as an egg heater, or the like.

Fig. '9, a similar view of the same, the reciprocatory or handle member being in advanced position preparatory to its return movement whereby the spiral member will be moved longitudinally out of engagement with the reciprocatory member for a newworking impulse and permit of the continued rotation of the rotary member until the latter is given a new working impulse by the reengagement of the spiral member.

Fig. 10,0. similar view in which'a second reversely arranged spiral member is mounted outside of the first spiral whereby a con tinued driving motion is imparted to the rotary member during the return as well as the advance or forward movement of thercciprocatory or handle member.

Fig. 11, asimilar view in which the inner spiral member is in action and in clutched relation to'the reciprocatory member while the outer spiral member is out of action andout of clutched position (in contrast to the positions shown in Fig. 10) and preparatory to the return of handle member for re leasing the inner-spiralmember and bringing ti outer spiral member into actionas shown in Fig. 10.

Fig. 12, a cross sectional view of the same taken on line l2--12 of Fig. 10.

Fig. 13, a view of the outer spiral member removed.

Fig. 1d, a view of the inner spiral memtively, through the mediumof amodified'or improved form of clutch carried by the reciprocatory member.

Fig. 16, a cross sectionalview' of-thesame taken on line'16.1'6 of'Fig. 15, the ball of the improved clutch, however, being in clutched position.

Similar numerals of" reference designate like parts throughout all the figures of the drawings;-

The improved mechanical movement comprises a reciprocatory or handle member 1, and a-rotary member 22, and as a means of transmitting rotary motion to the rotary member 2, through'the reciprocation of 'the reciprocatory member 1, a spiral 3, is interposed between the members 1, and 2, in cooperative relationtliereto, and in accordance with the particular demands or requirements of the article or device in whichthe' improved movement may be embodied.

As a means of bringing the spiral member 3, into and out of engagement with-one of the members uponthe initial advance-and return movementsoat the" reciprocatory or handle member 1, whereby rotary motion isimparted-through said spiral 3, to theretary member 2, and the latter'and said "spiral member are released upon and during the return movement of the reciprocatory'memher, a suitable clutch or engagingmei'nber 4', may be provided;

The elements 1, 2, 3, and 4-, may be oiany suitable and convenient form as suggested in the drawings, itbeing obvious that the iniproved movement is capable ofa variety of usesand applications of which those-herein shown and described are merely illustrative.

For example, the reciprocatory or handle member 1, may be mounted upon or in a suitable guide or support 5', and the latter may take variousforms, as for example, asa surrounding tube or casing as shown in Figs; 6, and 7, of the drawings, and in Figs. 15, and 16", of-the' drawings, or in the form of' supporting guide or frame members as shown in Figs; 8. to 11, inclusive, thereof;

As sh'owni in Fi s, 1', to 14, inclusive, ofth'e' drawings; thespiral 3, maybe formed of tl'i'e single lengthof spirally-wound sheet metal suitably spaced apart to form the spiralgrooves or recesses 3 and when so formed is adapted to have a circumferential and a limited longitudinal movement betweenthe reciprocatorv and rotary members 1, and 2, whereby the clutch 4:, is adapted to come into and out of engagement with one of said members upon the initial advance and returnmovements of the reciprocatory member.

The clutch 4-, may'take the form of a pair of engagingprongs adapted to be seated. in and to engage with a suitable stationary portion of the reciprocatory or handle member-1 as shown' in Figs. 1, to 5, inclusive, and Figs. 8-, to 11, inclusive, of the drawings, said prongs, in-thefirst instance, engaging on opposite sides of a cross pin it, and in the second instance, engaging in a pair of'openings 4 in the top of thehandlel. If desired, however, the reciprocatory or handle member 1, may extend witli inth'egspiral member 8, and operate the latter'through-the medium of a stud or projec tion 1*, as: illustrated in Figs. 6, and 7, of the drawings, and in which instance, the rota ry mei'nber 2, is attached-to (or may form a part of) a suitable rotary member as for,

example,a top body 2. In this instance,

therotary member 2, is provided with a pair ofopenings 4, to receive the clutch projections 4.

As a means of holding the rotary member or' 'sha nk 2, of the screw driver in a statiouaryor' locked position when the reciprocatory' or handle member 1, is fully advanced-so that the shank or blade 2, of the screw driver may be used as an ordinary screw driver, or in other words, without bringing the spiral feature into operation, the topof'the shank or rotary member 2, may be provided with a central notch or recess 2, to receive and contain and inter-- lock with the cross pin 4, as shown most clearly in Figs. 1, and 5, of the drawings.

The'rotary member 2, in. the forms shown iii-Figs. 1, to 5, inclusive, andin Figs; 8, to 12, inclusive, is provided with stud orpro jection 2 adapted to travel within or traverse the spiral recesses 3 in an obvious manner, and as a means-oi retracting or re turning the reciprocatory or handle member 1, to-its initial or retracted position in the forms shown in Figs. 8, to 12, inclusive,.of the drawings, a compression spring 6, may be mounted within thehandle 1, and between the head of the latter and a support or head 5, of the stationary support or frame member 5, and operating in an obvious manner.

In the form shown in Figs. 10, and 11,

however, the spring 6, may be dispensed saith spira l being oppositely arranged and disposed and being adapted to be brought into engagement with the stud of projection 22 0f the rotary member 2,'upon the return or retraction of the reciprocatory or handle member 1, so that the inner and outer spirals are alternately brought into and out of operative engagement with the rotary member 2, and the latter is driven during both the advance and return movements of the reciprocatory or handle member 1, as hereinbefore explained; The form of the outer spiral member being the same as the inner, it need not be explained in detail, and it will be observed that the clutch projections 4, thereof fit into a pair of openings 4, in the lower end of the handle and perform a func tion similar to those of the openings 4, at the opposite end of the handle as hereinbefore explained.

In the form shown in Figs. 15, and 16, of the drawings, the spiral 3, comprises two lengths of wire wound about the rotary member 2, in a stationary or fixed manner and the spiral is brought into and out of engagement with the handle 1, upon the initial advance and return movements of the same, respectively, through the medium of.

an improved clutch carried upon the handle member 1, said clutch comprising a ball clutch 7, loosely mounted in a casing 8, the latter being provided with openings 8, to receive and to traverse the spiral 3, and forming an annular ball race-way 8*, so that at the end of the working stroke of the handle member 1, or upon the initial return of the latter the force of gravity will hold the ball 7, within the race-way 8 and permit the convolutions of the spiral 3, to travel about and carry with them the ball 7, in

the ball race-way 8", but upon the initial advance or return movements of the handle the ball clutch 7 will find its way into one of the recesses 8, (see Fig.16) so that upon the return or downward movement of the handle 1, the ball will remain seated between one of the recesses 8, and the adjacent spiral and cause the latter to be rotated until pressure is released to permit the ball to drop by gravity and find its way into the ball raceway 8". I

It will also be observed that in all in.- stances the axially located rotary member 2, not only projects from or extends beyond one end of the reciprocatory and spiral members but that its end or terminating bearing portion is arranged within the common axial planes of said members.

From the foregoing description taken in connection with the accompanying drawings, the advantages and operation of my invention will be readily understood.
